A number of the SDK components require GUIDs (globally unique identifiers). A tool to generate these is included with both Visual Studio and Visual Studio Express. Alternatively, you can download the GUIDGEN tool from:
This will place an icon on the desktop, called GUIDGen. Open this up and double-click GUIDGEN to open up the tool
For most applications, choose option 4. Registry Format as the most appropriate GUID format.
Click New GUID as many times as necessary. It is not a good idea to manually modify existing GUIDs, as the chances of repeating an existing GUID is greatly increased by doing this.
